Patent CA-2163296-A1 (CA)
Inventor: DUFOUR YVON
IPC: B65G45/12
Filed: 1995-11-20
Abstract: La présente invention a pour objet un appareil pour racler la surface de la courroie d'un convoyeur et son usage pour le nettoyage de la courroie d'un convoyeur de pièce de viande. L'appareil comprend une barre de support rigide, des moyens de fixation et une racle. Les moyens de fixation sont prévus de manière à fixer la barre de support au-dessus du convoyeur à une certaine hauteur et avec un angle dit "de gratte" entre la barre et la direction de défilement de la courroie. La racle, sensiblement de même longueur que la barre, présente une arête inférieure. Elle est fixée à la barre de support de manière à ce que son arête inférieure effleure la courroie avec un angle d'inclinaison par rapport à la surface de cette courroie afin de mieux déloger les produits collés à la courroie. L'angle "de gratte" ainsi que l'angle d'inclinaison sont choisis de manière à ce que lorsque des produits sur la courroie entrent en contact avec la racle, ils se trouvent non seulement décollés mais également entraînés sur eux-mêmes jusqu'au bout de la racle. A ce moment, la surface de contact de ces produits ainsi décollés de la courroie est alors réduite au minimum et sa masse est au maximum. Ceci permet donc de les recueillir par simple gravité.

Patent CA-2174042-A1 (CA)
Title: Solvent flush reaction injection molding mixhead
Inventor: SALISBURY WAYNE G
IPC: B29C45/24
Filed: 1996-04-12
Abstract: A solvent flush reaction injection molding mixhead has a mixing chamber with a solvent inlet port in one end and a chemical outlet port in an opposite end.    A  pair  of  hydraulically  operated  chemical injectors are connected to the mixing chamber between the solvent inlet port and chemical outlet port and at directly opposite locations and inject liquid reaction molding chemicals at high pressure through  injector ports into the mixing chamber.  The injected chemicals impinge at high velocity on entering the mixing chamber resulting in their thorough mixing and are delivered through the chemical outlet port to a spray wand on the mixhead for spraying onto a mold surface or an object requiring a foam coating.  A flush valve is connected by a piston rod to a hydraulically actuated piston and is moveable thereby from a closed position closing the solvent inlet port against the force of the chemicals injected into the mixing chamber to an open position where the flush valve uncovers this port.   A liquid solvent under a high pressure but less than that of the injected chemicals is supplied to a solvent feed passage that extends through the flush valve piston rod and piston into the flush valve where it communicates with solvent feed ports in the flush valve that are blocked when the flush valve is in its closed position.  In its open  position  and  following  a  dispensing  of  mixed chemicals, the solvent feed ports in the flush valve are opened  to  the  turbulator  ports  which  then  deliver turbulent solvent flow under high pressure to clean and flush any remaining mixed chemicals  from the  flush valve,  the  mixing  chamber  including  the  chemical injector ports, and the spray wand.
